Permafrost study finds abrupt thaw accelerates soil phosphorus cycling, offsetting carbon release

Permafrost thaw can stimulate the release of soil carbon, triggering a positive carbon-climate feedback that may be mediated by changes in soil phosphorus (P) availability. A research team led by Prof ...
